Watson-Marlow has introduced three NEMA-4X-rated cased peristaltic pumps with Profibus DP networking capabilities. The 520, 620 and 720 series pumps are suitable for metering or transfer of slurries or viscous, shear-sensitive and aggressive fluids without contamination of the pump or fluid. The integrated Profibus capabilities make it easy and efficient for technicians to integrate the sealless, valveless pump technology into their Profibus control system. In addition, the resulting reduction in the complexity of installation wiring, and associated engineering time and hardware, lowers capital cost. Diagnostic capability and speed of responsiveness are increased, cutting plant downtime and maintenance. A second pumphead option doubles the maximum flow rate to 17.6 gpm on the 720 series pump.
